Researchers at the University of Vermont sifted through more than 10 million geotagged tweets from 2011 to map out the moods of Americans in urban areas. They ranked the locations based on frequency of positive and negative words using the Mechanical Turk Language Assessment word list.

The study, which was broken down by The Atlantic, also looked at the results for 373 urban areas to rank the happiest and least-happy cities. Vacation destination Napa, California, was determined to be one of the happiest cities along with Longmont, Colorado; San Clemente, California; Santa Fe, New Mexico; and Santa Cruz, California.
